Modification of the Stages in Total Reconstruction of the Auricle

Among the microtic disorders, those with the remnant ear, ear lobule, concha, acoustic meatus, tragus, and incisura intertragica are classified as concha-type microtia. From these characteristic factors, concha-type microtia has been thought to be a milder form of microtic disorder in comparison with lobule-type microtia. The constructed modified three-dimensional costal cartilage framework is grafted to the superior portion of the auricle and fixed to the inferior remnant cartilage of the auricle (conchal portion). This may appear to be a simple procedure in comparison with the other microtic disorders, but it is extremely difficult to fix the modified three-dimensional framework to the remnant auricular cartilage so that a smooth configuration is attained at the seam. In this paper, the modification stages for total reconstruction of the auricle for concha-type microtia are discussed.
